[Non capture guide rod for Sig P320 Compact]

One solution I'm thinking might work is a correctly sized recoil spring plug with an end hole, like on a 1911.

 

A modified version of one of these:

[Non capture guide rod for Sig P320 Compact]

Does anyone know where I can find a non capture guide rod for a Sig P320 Compact?  I see GGI make a fat rod for the full size version, but have drawn a blank trying to find anything for the midsize Compact.

 

Thanks.
